I thought I asked this... but am I supposed to turn invisible after Mordack and Manannan talk?

When I return to the Wizard, I get killed for carrying contraband when all that I am carrying is an empty jar, some fruit, and the rope. None of these are magical items. When I try to get firewood, the tree where I had gotten it in the past is moldy. If it's the jar you got from his lab, then obvio...

I meant on my second journey, it won't continue the plot unless I break into the bears.

Probably known Bug:

After Mordack and Mannanan finish talking, Gwy turns invinsible. And never changes back.

Also, does the plot end when Manannan is in his office, on Day...5?

How do I get the three bears key? I'm guessing I need to find a hook somewhere? (Has the line) And is that all I need before I can return to the mountain top?
